Graphs of the Other Trigonometric Functions · Exercise 54

The function $f\left(x\right)=20tan\left(\frac{\pi }{10}x\right)$ marks the distance in the movement of a light beam from a police car across a wall for time $x,$ in seconds, and distance $f\left(x\right),$ in feet.

ⓐ Graph on the interval $\left[0,5\right].$
ⓑ Find and interpret the stretching factor, period, and asymptote.
ⓒ Evaluate $f\left(1\right)$ and $f\left(2.5\right)$ and discuss the function’s values at those inputs.

Its source prints no answer for this problem, so there's nothing to check against.
